Application filed May 19, 1909. Serial No. 496,915.

T 0 all whom it concern:

Be itknown that I, HERMAN Loc uv LAM- BRECHT, a citizen of the United States, and a resident of Sullivan, in the county of Moultrie and State of Illinois, have inventeding drawings forming a part of this speciengage over the keeper.

fication, in which similar characters of reference .indicate corresponding parts in all the views. 1

Figure l is a view of a hasp latch embodying my invention as applied to a door; Fig. 2 is a central longitudinal section through the latch; Fig. 3 is an inner vface view of the latch bolt; and Fig. at is a similar view of the outer section or swinging portion of the hasp.

In the construction of a hasp fastener in accordance with my invention, the hasp proper 5 is hinged at its inner end toa leaf 6 provided with a number of screw-openings for applying it to-the door or gate, the

outer end portion of the hasp having the usual slot 7 arranged to register with a keeper 8 which, in the present instance, is shown to be a plate having a lock aperture S) and a notch or recess 10 at its forward edge, the keeper being also provided with a base having screw-openings for attaching it to the door jamb or a gate post.

A latch is carried by the hasp and consists of a latch bolt 11 and a spring 12, the latch bolt, like the'hasp, being constructed of a strip of sheet'metal of approximately the same width and having a slot 7 in its outer end portion, similar to the slot 7, to The bolt 11 is also provided with a number 'of slots 13, three being shown, two located side by side, intermedia-te the length of the bolt, and the other slot arranged at the rear end portion of the bolt. Rivets 14 secured in the hasp. pass through the intermediate slots 13 and slidably connect the hasp and latch bolt together. Between the intermediate and rear slots 13, the latchbolt is'stamped outwardly in the form of a semi-cylindrical casing 17, longitudinally arranged and having an inwardly-projecting pin 18 at its inner end.

The hasp at a point opposite the forward end of the casing 17 has a tongue 19 stamped outwardly therefrom, which forms an abutment for the spring 12 which is located in the casing 17 and held in place on the guidepin 18, the spring operating to force the bolt inwardly. hen the latch bolt is in its innermost position, the rivets 14 contact with the forward ends of the intermediate slots 13, and the latch bolt is moved inwardly to carry .the keeper slot 7 a. substantial distance out of register with the 'slot 7 in the hasp, whereby the bolt will be drawn into the notch of the keeper when the hasp 1s swung to a closed position, as shown iii Figs.

1 and 2. The outer end portion of the keeper is rounded, as is the general, practice, and

acts as a cam to automatically retract the latch bolt when the hasp is passed over the keeper, thus enabling the latching of the hasp to be performed automatically. Both the outer end of the hasp and the outer end of the latch bolt are curved outwardly to provide finger-pieces to retract the latch bolt when the hasp is to be withdrawn.

Having thus described my invention, 1
